' ICOBBLE BUNDLER Filed June 6, 1945 2 Sheets-Sheet 2 INVENTOR v CHARLES wHAw-moRuE AT'roRr lElY Patented Aug. 31, 1948 Charles: W: Hawthorne, Conneautville;. 2a., assignontQMoman (lonstrucltionfl mnany, Worcester, Mass-.;, .a, corporation; of; M31553?- ehusettsz ApplicationJune-G;1945, scrial No; 5973809" Thisl inven-tion relates tovcobbleibundlers; and? morelparticularly to machines for'coiling waste rods: 01 1 bars in i metal rolling; mills; and 1 similar plants; in order. toformlcoils. or bundlesrwhichmaybe readilyhandled.

In my: prior: Patent No. 2083,263 granted- June 8, 19.37: there is: disclosed a machine comprising a horizontalrotatablearborwhich extends-into a: casing; the latterbeing supported-- on rails. for: movement I parallelawith the arbor. The.-a-rbor. is 1 provided with a screw-thread, and theeconstruc -fl tionlistsuch that by-rotatingthe .arbor inton ldierection; a bundle Willibe formed thereon within" theeasing. Then by reversing the rotation of" the arbor,- the bundle will be forced axially from the arbor by; the action ofthe screw-thread, pushingthe casing alongs-the rails; whereupon-the: bundle .willbe aejectedlaterally from thecasing;

In :theaoperation ofthis: prior construction thebundle -.occasiona+lly engages the walls of "the easing so: tightly; that it wil1 not be ej ected automatically; Infaetjconsiderable:difiiculty may been-- countered: inremoving the bundleunder these circumstances;

It; is; accordingly one: object or the-"invention to;- provide a..cobble bundler ofra' novel'constructionsuch as: to vgreatly facilitate the. discharge of the completed bundles.

It is a further object-of the invention to -improve theconstruction disclosed in my abovementionedprior patent by preventing the bundles from engaging the wallsofthecasing tightly.

It is a: further obj ect of "th inventionto pro vide-a cobble bundler which--canzbe depended uponto eject the completed bundles-automatically.-

Withthese and other objects-inview', as willbe apparent to those skilled in the art, the invention resides-in-Vthe combination of partsset forth inthe specification and: covered by the claims appendedhereto.

Referringto the drawings-illustratingone embodiment I of the invention and in which llke-ref erence=numerals indicate like parts,

Fig. 1 is-a front elevation of a 'cobblebundler;

Fig. z-is asectional planview of themachine, taken approximately on the line 2-2"ofFig, 3 with the gear box cover removed;

Fig. 3 is an end-elevationof the machine, viewed as indicated by.theline; 3:--3tof Fig,; 1; and

Fig. 4 is a section taken on the line 4-4 of Figgl.

The embodiment illustrated comprisesa-horizontal rotatable-arbor llllhaving at' one end a flange ll which is secured to a similar flange, l2 on oneend of a horizontal shaftl4. This shaft is supported-in spaced bearings l5-l5' carried by a gear boxl6 which-in turn-rests on a base-l8. A gear 19 is secured to the shaft l4 between the bearings l5, and this gear is driven by means of a pinion 20 carried by a second horizontal shaft 2 22 parallel to the shaft [4 ported in. spaced .1 bearings box IS; A .gear24 ismountedon the shaft:22;, andi'this {gear is driven by a pinion 26 on a shaft 21 which-:isconnected by-a coupling 28 tootheshaft of a reversible electric motor 29; With this construction the arbor l0 can be rotated in either! directionv at' a speed considerably lower thanithat of themotor 29. The arbor is provided onits outersurface with a helical rib-3| forming:

a screw-thread; which preferably-has a-relatively coarse lead; Inthe unsupportediend of the arborthere isprovided'a slot 32 which preferably ex-- tendsthrough the arbor diametricall and is .arrangedin tially the same leadas the tion; reference may. be: No..2',083;263.

The arbor lll'isenc1osedby a':casing-34 having a pair of'upright side walls 35--35 spaced apart in an axialdirection, a-bottom wall 36; and a rear wall 31 which forms a continuation of the bottom wall. The bottomgwall'3fislopes downwardly and forward-lyvtoflanopening 39 at the front of the tending through .onez ofz theseopenings and into thepother: A heavy roller 4 l is mounted within; the,- casing: 34, above the: arbor l0 toe, force thestock; into: firmengagement with: the arbor, therollerbfein carriedibyahorizontal shaft 42 which extends: beyond the; roller at" each end to formtrunn-ion-sgwhich' are-located; within vertical slots 43-43 in the side walls 35; The casing 34'is sup-r portedzforshorizontal movement parallel with the arbor; so-that the bundlesjmay be readily stripped;

from-the arbor.- In order to-facilitate this movementthe base l8=is providedwith a pair 0f'hori-.

zontalrails 45:"which support four wheels 45 rotatablysecured to: the lower. portion of the casing- 34lbymeans'tofpins or shaftslll; Bumpers 49' limit the'inward" movement of'the casing to the coilingrposition; and other bumpers 50 limit the outward movement of the casing to the dischargeposition indicated by the brokenlines in Fig. 1;

As the-metal'rods approach the arbor II) for coiling thereon, they are guided in such a way that thecOmpIetedbundle will be relatively free from; binding" against the casing sidewalls 35. For-this purpose; a guide structure inthe form of {a hollow-*frame52 is mounted in a fixed posi tion-in-frontof-thearbor l0. This frame'52isprovidedwith'two side walls,53-53,' a bottom wall-54; and a top wall '55, all of which converge rearwardly toward a rectangular opening 51. When the casing 34 is in the coiling position, the casing opening 39 will be directly behind and aligned with the guide opening 51, as shown in The shaft 22 is sup- 23-23 carried by thea h'elix-of the same hand andcsubstanscrew-thread 3 I. For a more complete disclosure of the arbor-construc-.

had to my prior Patent 3 Fig. 2. The width of the guide opening, between the rear portions of the side walls 53;thereo'f, 'is' substantially less than th distance between the side walls 35 of the casing 34. As a result of this construction, the rod which is being coiled upon 1 the rotating arbor l Will be guided away from the side Walls of the casing, and the finished bundle rect the rod through the opening intothe casing, the guide means providinga guide opening having a widthappreciably less thanthe width of the casing opening, and means to support the casing ior'movement in an axial direction so that the completed bundles may be stripped from the arbar and ejected through the casing openin with- Will fit comparatively loosely within" the casing.

The operation of the invention will now be apparent from the above disclosure. With'the casing 34 located at its inner or coiling position against the bumpers 49, as shown in Fig. '2, t e operator will pass the front end of the rod or bar through the guide opening 51 and the casing opening 39 and insert it in the arbor slot 32. Thereupon the arbor l0 will be rotated in'a countar-clockwise direction, as viewed'in Fig. 4, and

the rod will be wound upon the arbor, the heavy roller "41 pressing the convolutions together to provide a closely compacted bundle. The guide frame 52 will direct the rod away from the casing side walls 35 and thus preventt'he bundle 1 from wedging tightly within the casing: "When" thexbundle is completed, the'rotationof; the ar borlO will be reversed, and the'threads 3| will.

force'the bundle axially from the arbonpushing the casing 34 along the rails 45. The bumpers 50 will stop the casing in the position indicated by the broken linesin' Fig, 1, and the bun'dle'will' roll forwardly through the opening 39'under'the influence of gravity, aided by the Weight of the roller 4|. Since the bundle fits loosely within the casing and is free from bindin againstthe. side walls, this ejection will take place .automatically in a thoroughly dependable-manner.

Having thus described my-invention,-what 'I' claim as new and desireyto Patent is:
